Building a neighbor a little mill

[97fishmt]

Just about done with it.  Painting and wiring left.
The blades are at the cabin.  I made this to fit
over a 2" water pipe since it will only be a 6' prop.

A taper lock hub on this one.


Real easy just angle iron and pipe or tube.

A little flat stock for the tail mounts.

Lots of fun

I see a lot of the KISS principle applied here.
Compact and tidy!
...and aren't those taper-lock sprockets just the handiest things for little blade hubs, eh?

[97fishmt]

Yep,  I'm right at about $100 including the blades.
I bought enough steel for 4 units like this and spent
$100 so $25 for the steel  that even includes a 10'
section of 2" pipe for me to test it out.

I made the face angle long to maybe accommodate
a wider motor.  I'll cut it to fit after I check out the other
motors at the cabin.  I think they are 8" wide, this one is 6".

The taperlock sprocket was collecting dust at surplus center
in Nebraska.  I got the last two for $11 and that included shipping.

I'm digging getting better at MiG welding but, I sure would like to
step up and get the gas set up.  I'm using flux core wire.  I know
the difference, I have welded with argon at work.  It is like night
and day.  Anyhow just going on the cheep here.  Might get a cord
or two of firewood for this little gem.

That's  a neat machine your building. IT proves You don't need To spend  A lot of money To make something useful.

It's good to see that you have given it some thought and included furling, usually simple machines get subjected to the full force of the elements and fail to survive the first big storm.

Looks a nice machine.

in know way to i consider myself an expert welder even tho i do alot at work (mostly sheetmetal) but in my experience if you clean tthe flux out between multiple passes...and dont mind grinding off the spatter when done, you usually get deeper penetration with fluxcore because you are using dc negative. the structural welders at our factory use 'dualshield' a fluxcore wire that also uses a shielding gas. 

using plain wire does give a cleaner weld but to me it doesnt give the penetration...and is extremely hard to use outdoors, where every stray gust blows the gas away

It looks to this pro like you are doing just fine with flux core, actually much better than a lot of week end warriors do with gas shielded mig.

This is an interresting little setup... Do you think you could give a little more info on what all had to be done to convert the servo motor?
